Despite trying all available solutions, importing bookmarks from Chrome does not work in this firefox latest version 150.0.1. When importing Bookmarks from Chrome, the Saved Passwords file is fully imported and shows 163 Nos. imported. But on opening Firefox, nothing is there. No folder contains imported bookmaks. Tried importing several times, but to no avail. Uninstalled, restarted PC and reinstalled firefox. But importing Bookmarks and Passwords from Chrome sucks. I am fully aware of the procedure. So no more detailing needed. Using firefox since the last 16 years. But the software makers are simply spoiling a good browser by deliberately creating issues. Tried importing from saved html file of bookmakrs, but that also is not helpful. Why Firefox is deliberately causing such errors with updated versions? Please release next version after thoroughly checkining this importing feature and ensure that it works correctly. I tried uninstalling, restarting the PC and reinstalling with with full offline installer as well as online installer. Nothing helped. Chrome works smoothly. Earlier firefox did not have any such issues. With each update, problems after prblems started creeping in with someone deliberately tweeking the software and spoiling a good browser. Please look into it seriously and provide a solution.

No Bookmarks (which are shown as imported from Chrome, almost 163 number of Bookmarks) are visible anywhere in Firefox. They are neither stored in the Bookmarks Tool Bar nor in any folder named Imported from Chrome. This is the situation. Uninstalled Firefox, removed all Folders (including the ones in hidden folders) and cleaned the Registry. Restarted the PC, reinstalled Firefox directly from the firefox site online, tried importing the Bookmarks from Chrome after restarting on installation of Firefox. Saved All passwords from Chrome as a CSV file (a Firefox requirement) and tried importing Bookmarks from Chrome along with the Passwords from the CSV file saved on Desktop. Again, the importing showed 163 Nos. of Bookmarks are imported. But on restarting Firefox, no bookmark could be found. Neither in the Bookmarks toolbar nor in any folder named with any name. My Bookmarks toolbar is checked as Always visible. I DO NOT KNOW WHAT TO DO NOW TO MAKE THE FIREFOX WORK as in the previous version. This kind of an error has crept only after updating Firefox to v150.0.1.

When watching twitch and I open another tab, the new tab is very slow to open a web page and sometimes wont open at all just keeps scrolling. Any suggestions how to solve this problem?? I tried with Opera and it doesnt have that problem?? Dont want to give up on Firefox as I like it the most. Any help much appreciated.

My old laptop is broken; I can no longer access the hard drive. Is there any way I can reorganize my old bookmarks from before a specific date, i.e., December 15, 2025, in Firefox?

I recently bought a new laptop running on Windows 11 Pro. All my settings for languages (English GB) in Firefox are the same as my old laptop, which was Windows 10.

On my W11Pro laptop, the translation icon doesn't appear when I highlight a portion of text in a foreign language, whereas it did appear in my old laptop. If I right click on the highlighted text I can access "translate selected text" but nothing happens when I click on that. Translating an entire webpage works fine, it's just the highlighted text that doesn't.

I'm not very technically minded, so any answer will need to be in simple terms! Thanks.

Hello. I have a question regarding a problem with exporting files in Firefox. For about four days now, when I try to export files in Firefox, it fails. I've looked into it, but haven't been able to find a solution. Could you please give me some advice? I've tried various things within my capabilities, but nothing has worked. Firefox 150.0.1 64bit

How can I resolve the failure to open because it can't find the XPCOM. I downloaded a new copy but the computer insists on using the older, faulty version to open files and it will not work.

the last update of firefox wiped out my amazon account on my pc. It completely cleared my calendar. Messed with my passwords on some of my accounts. Can someone tell me how to get these things back. I am not a computer wiz.

Good morning. I am looking forward to the VPN service being offered for free through Mozilla. I see that the rollout has happened in the US but I haven't seen it yet. I have been using Mozilla for years and wasn't sure if the US had been fully covered yet or not. Thanks and have a good morning.

I am subscribed to a newsletter and ever so often firefox doesn't allow communication with the comments. This has happened several times and I have always corrected the problem in firefox, I have forgotten how I corrected the problem, For me this is an ongoing problem any suggestions?

A pain in the ass I do not want updates I have it marked on settings every update I get screws up computer I do not do a lot except stock market then take a nap I am 88 and not interested in playing games or silly stuff

after the last update of firefox, the default firefox home page doesn't load. Instead, I get the message: Oops, something went wrong loading this content. Any ideas?

About a week ago I had printed 2 copies from my Firefox browser. Next time I only needed 1 and changed it. Since then it stays at 2 and no matter what I do it won't go back to one.

How do I fix this?

When I click Bookmarks > Manage Bookmarks I'm taken to Other Bookmarks where I never store anything. I'd delete it if I could but it doesn't appear to be an option, so instead I'd like to taken directly to Bookmarks Menu. I came across this post from just over 4 years ago which sounded like it's exactly what I want, but it doesn't work. Are there any changes anyone can suggest that would allow it to work in 2026?

You can use the autoconfig.cfg file in the Firefox installation folder to initialize (set/lock) preferences and run privileged JavaScript code. In this case code to open the Library with the Bookmarks Menu folder selected. You can modify the showPlaces variable to open any of the four possible root folders (in this case [1]).

To use Autoconfig, place two files into the Firefox installation directory.

   on Windows and Linux, they go into the same directory where Firefox is installed
   on macOS, they go into the Contents/Resources directory of the Firefox.app 

The autoconfig.js file that specifies to use autoconfig.cfg is placed into the "defaults\pref" directory where the channel-prefs.js file is located.

The autoconfig.cfg file is placed at the top level of the Firefox directory.

   autoconfig.cfg and autoconfig.js need to start with a comment line (//)
   autoconfig.js needs to use Unix line endings (LF instead of CR/LF) 

See also:

   https://support.mozilla.org/en-US/kb/customizing-firefox-using-autoconfig 

Content of autoconfig.js

//
pref("general.config.filename", "autoconfig.cfg");
pref("general.config.obscure_value", 0);
pref("general.config.sandbox_enabled", false); // disable sandbox to allow privileged JavaScript

Content of autoconfig.cfg

// first line in autoconfig.cfg is a comment line try {

let {classes:Cc, interfaces:Ci, manager:Cm, utils:Cu} = Components;
var Services = globalThis.Services || ChromeUtils.import("resource://gre/modules/Services.jsm").Services;

function ConfigJS() { Services.obs.addObserver(this, 'chrome-document-global-created', false); }
ConfigJS.prototype = {
 observe: function (aSubject) { aSubject.addEventListener('DOMContentLoaded', this, {once: true}); },
 handleEvent: function (aEvent) {
  let document = aEvent.originalTarget;
  let window = document.defaultView;
  let location = window.location;
  if (/^(chrome:(?!\/\/(global\/content\/commonDialog|browser\/content\/webext-panels)\.x?html)|about:(?!blank))/i.test(location.href)) {
   if (window._gBrowser) {
     let showPlaces = ["AllBookmarks","BookmarksMenu","BookmarksToolbar","UnfiledBookmarks"][1];
     elm = document.getElementById("Browser:ShowAllBookmarks");
     if (elm) {
      elm.setAttribute("oncommand", "PlacesCommandHook.showPlacesOrganizer('"+showPlaces+"')");
     }
   }
  }
 }
};
if (!Services.appinfo.inSafeMode) { new ConfigJS(); }

} catch(e) {Cu.reportError(e);}

I have my credit card info correctly saved in the FF settings on my PC desktop, but it doesn't work correctly on some online forms.

When it fails to work I click on the truncated information for the saved credit card I wish to use, but it fills in later numbers in the sequence incorrectly with the wrong digits and too few numbers to even be a legitimate credit card number

I have double checked in the settings, "privacy and security", and the credit card numbers are entered correctly there and enabled.

The form I have most recently had issues with were for a local "big day of giving" site, and it is powered by something called "mighty cause."

I can't include a screenshot of the issue itself occurring or my settings, for obvious reasons.

My PC is windows 11 home edition, and the version of Firefox is 150.0.1 (I think).

ie every time I closed it it would reopen- 14 times when I am trying to read my emails yesterday and 6 today. but I thought it was my internet security causing the problem. I kept getting notification that a certain site was attempting to use my system,. The worst thing was it kept flashing on my screen and wouldn't go away, There was no clue who öwned it, my security or Mozilla's. It was finally resolved by contacting my computer guy, but we never identified the source. the site that was being blocked started with pssst.........com, or something similar but it was driving me mad trying to get it off the screen. If this happens again, how do I get rid or stop the continual notifications? Of course I have nothing to show you as I have since deleted it, sorry. as I was just relieved to see it gone.

Thank you Angela Johnson

When I press F12 to use the developer tools and try to change the width of the panes by click and drag the divider there now seems to be a limit to the panes width that was not there before. I'm not sure with what version I stated to notice this. I use to be able to drag the right hand panel fairly far over to the left and could take up about 75-80% of the width of the developers window. Now I'm guessing that I'm able to drag the right panel to a max width of 35-40% for some reason. I have not changed anything in the about:config page. I'm not sure why I can't drag the right panel to cover the 75-80% of the window that I had been able to do.

Is there a setting in the developer tools or on the about:config page that sets the max width that the right hand panel can be dragged to the left?

Went to VRBO website to look at a reservation and the website, which showed me as signed in, showed nothing of the reservation. Said I had no reservation,, no history of saved searches. When I used Microsoft Edge, all my previous reservations, searches etc. were accessible. I cleared my Firefox cookies, etc. still had the same problem

Steps that remove my pinned tabs from Firefox:

Open pinned web app from taskbar. Open regular Firefox browser.

Any pinned tabs that were in the browser before opening the web app are lost.

Is this already reported? I can't imagine this is intended behavior.
